摘要:

在本研究中, 我们制备了iRGD, CRGDK/RGPD/EC)修饰、含溶血磷脂的温敏脂质体(LTSL)载体系统用以递送共轭亚油酸-紫杉醇(CLA-PTX), 简称iRGD-LTSL-CLA-PTX。在B16-F10黑色素瘤细胞上评估了iRGD-LTSL-CLA-PTX的体外细胞摄取和体外细胞毒性。在荷B16-F10黑色素瘤的C57BL/6小鼠上评价了iRGD-LTSL-CLA-PTX的体内抗肿瘤作用。细胞摄取实验结果表明, SSL-CLA-PTX组相比, 42 ºC分别孵育246 h, iRGD-LTSL-CLA-PTX给药组中CLA-PTX的细胞摄取分别增加2.053.314.83倍。体内抗肿瘤效果表明, CLA-PTX溶液、LTSL-CLA-PTXLTSL-CLA-PTX(加热条件)iRGD-LTSL-CLA-PTX相比, iRGD-LTSL-CLA-PTX(加热条件)可显着抑制B16-F10肿瘤的生长(P<0.01)iRGD-LTSL-CLA-PTXB16-F10黑素瘤的体外和体内抗肿瘤作用得到证实, 这是iRGDLTSL共同作用的结果。

Abstract:

In the present study, we prepared the iRGD-modified lysolipid-containing thermosensitive liposomes (LTSL) containing conjugated linoleic acid-paclitaxel (CLA-PTX), also known as iRGD-LTSL-CLA-PTX. The in vitro cellular uptake and invitro cytotoxicity of iRGD-LTSL-CLA-PTX were evaluated in B16-F10 melanoma cells. The in vivo anti-tumor effect of iRGD-LTSL-CLA-PTX was investigated using B16-F10 tumor-bearing C57BL/6 mice. The results of the cellular uptake experimentindicated that the increased cellular uptake of CLA-PTX in the iRGD-LTSL-CLA-PTX-treated groups was 2.05-, 3.31- or 4.83-foldcompared with that in the SSL-CLA-PTX group after a 2-, 4- or 6-h incubation at 42°C, respectively. The in vivo antitumor results showed that iRGD-LTSL-CLA-PTX/heat significantly inhibited the growth of B16-F10 tumors compared with the CLA-PTX solution (LTSL-CLA-PTX, LTSL-CLA-PTX/heat and iRGD-LTSL-CLA-PTX) (P<0.01). In conclusion, the antitumor effect of iRGD-LTSL-CLA-PTX was confirmed on B16-F10 melanoma in vitro and in vivo, which was induced by both the effect of iRGD and LTSL.
